[ipv6-wg] Last Call (20101117): Requirements For IPv6 in ICT Equipment

Yes Marc,
but if they are optional... some will be mandatory. What will be 
mandatory for Ipv4 Mpls backbone ? ;)

If we use as mandatory dual stack the ipv6 vpn mpls not work. We must 
use 6VPE that is over ipv4. Today as you know LDPv6 is under 
developement by ietf and vendors will wait 1-2 years to deploy the 
protocol inside os. I think today and when ipv4 addresses will finsh the 
ipv4 mpls backbones remains the same ($$) and the 6PE and 6VPE will be used.
